Description

Technical Field

[0001] This utility model relates to the field of profile winding technology, and more specifically, to a highly stable automatic winding device. Background Technology

[0002] With the development and promotion of trenchless pipeline technology, the repair work of aging pipelines in various cities is gradually increasing, and the corresponding demand for repair base materials is also gradually increasing. How to improve production efficiency under the condition of full capacity and supply materials to on-site construction personnel in a timely manner has become the top priority for enterprises.

[0003] The previous production process involved separately winding the plastic extruded profiles and steel strip supports, then unwinding them simultaneously for steel-plastic compression molding to form a steel-plastic composite profile. This process involved numerous steps, was labor-intensive, and had low composite efficiency, thus affecting material supply during construction.

[0004] For example, CN219567011U discloses an automatic winding device, including a frame with a take-up tray pivotally mounted on the frame. The take-up tray can be driven to rotate by a drive assembly. A rotating shaft is pivotally mounted on the outer side of the take-up tray, and a pressing arm is fixedly mounted on the rotating shaft. A pressing wheel is pivotally mounted on the pressing arm and can always press against the take-up tray. A base is also fixedly mounted on the frame, and a conveyor line is pivotally mounted on the base. The conveyor line is located outside the take-up tray, and the conveyor line can be oscillated by a toggle assembly. However, this device is difficult to install the material roll, and the profile is prone to shifting. In addition, the speed and unwinding resistance of the material roll are unstable during unwinding, which can easily lead to shifting or displacement of the material roll, affecting the yield rate and having significant limitations. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a highly stable automatic winding device.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A high-stability automatic winding device includes a frame with a pivot shaft on the frame. One end of the pivot shaft has a clamping assembly for holding the material roll, and the other end has a damping assembly for limiting the position or speed of the pivot shaft. The damping assembly includes at least a first support plate fixed to the pivot shaft. One side of the first support plate has a connecting flange sleeved on the pivot shaft. The connecting flange and the first support plate are connected by a connecting spring sleeved on the pivot shaft. A friction disc is fixed to the connecting flange. A fixing flange is also sleeved on the pivot shaft and fixed to the frame. A pressure plate is provided on the fixing flange, and the friction disc can abut against the pressure plate.

[0008] Preferably, the outer circumferential surface of the friction disc is uniformly provided with notches, and a telescopic rod is fixed on the frame, the telescopic rod being able to extend at least partially into the notches.

[0009] Preferably, the frame is further provided with an encoder for detecting the number of rotations of the shaft.

[0010] Preferably, the clamping assembly includes at least a sleeve slidably disposed on the rotating shaft. The outer circumferential surface of the sleeve is fixedly provided with fixing strips at equal intervals. Both ends of each fixing strip are fixedly provided with driving strips. The other end of the driving strip on the same fixing strip is connected to a corresponding driving plate. A driving wheel is fixedly provided on one end of the driving plate. A second support plate is also fixedly provided on the frame. The second support plate is sleeved on the rotating shaft, and a driving groove corresponding to the driving wheel is opened on the second support plate. The driving wheel extends at least partially into the driving groove.

[0011] Preferably, the outer surface of the drive plate is an arc-shaped surface and is adapted to the inner wall of the material roll.

[0012] Preferably, a drive handwheel is fixedly provided on the end side of the rotating shaft, an external thread is fixedly provided on the outer circumferential surface of the rotating shaft, and an internal thread is provided on the inner wall of the sleeve, the internal thread being adapted to the external thread.

[0013] Preferably, bearings are fitted at both ends of the rotating shaft, and the outer rings of the bearings are fixed to the frame.

[0015] 1. The design is ingenious and the layout is reasonable. The friction plate and the pressure plate work together to adjust the speed and resistance of the material roll during unwinding, ensuring that the resistance and speed of the material roll are always consistent, avoiding the material roll from shifting or displacing, improving the yield of subsequent processing, and having a wide range of applicability.

[0016] 2. The telescopic rod can be inserted into the notch to precisely limit the friction disc, preventing the material roll from continuing to unwind. It is simple and reliable to operate, highly stable, and achieves precise positioning of the material roll.

[0017] 3. The extension or retraction of the drive plate can clamp or release the material roll, which is simple and convenient to operate, easy to disassemble, replace and maintain, greatly improving work efficiency. At the same time, the layout is reasonable and the structure is compact, reducing the space occupied. Attached Figure Description
